Honestly, I feel that most of the kids are impressive. They all know how to sing for sure. I really like the sound of Vansh Wadhwa. I am rooting for him mostly, but still I feel like they are all generally good.
Many kids get 100. But some 100s are just so much more. He is showing the judges his range, control and creativity by taking on very difficult songs and executing each one to perfection with his own added touch.
His Dil Se performance and breath control in that was beyond belief.
